IMPROVEMENT lN LANTERNS.

Specification forming part of Letters Patent No. 141,311, dated July 29,1873 application filed October 29, 1872.

To all whom it may concern:

Be it known that I, LEWIS F. BET'rs, of

Philadelphia, Pennsylvania, have invented Improvements in Lanterns, ofwhich the following is a specification: The objects of my invention are,first, to simplif'y the construction of the upper part of a lantern;and, second, to reduce the strain upon the hinge by which theoil-reservoir is connected to the body.

The first of these objects is attained by hinging and connecting thedome G of the lantern to the wire frame or guards H by means of itsflange G, which, at one side of the dome, is simply wrapped around theguards so as to form a hinge, I), and at the opposite side is bent tothe form of a hook, also adapted to the guard-wires. By. thus formingboth the hinge and hook in one piece with the usual flange G of the domethe usual separate hinge and hook, which add to the cost of the lantern,and which require to be soldered or riveted to the flange, can bedispensed with.

If air were permitted to pass uninterruptedl y through the space abetween the two portions of the lantern to the burner, there would, incarrying the lantern about, he a constant flickering, and in some casesan extinguishing of the flame. To prevent this, I attach a cupshapeddeflector, I, to the lower portion of the burner, and extend the sameupward to a point above the space a so as to form a narrow annularspace, h, between the same and the body of the lantern, through whichthe air can pass upward to feed the flame, without disturbing thelatter. In carrying the lantern, rays of light will be directed downwardthrough the spaces a and h onto the ground. In the present instance thebody of the lantern is hinged to the oil-reservoir at i, and secured tothe same at a point opposite the hinge by a spring catch, 3'; but otherconnections may be used.

The lower ends k of the guard-Wires H extend through the body of thelantern, and rest upon the top of the oil-reservoir, as shown in Figs. 1and 2, thus supporting the upper portion of the lantern, and reducingthe strain upon the hinge or other connections. They also fit snugly inthe annular space h between the deflector and the body of the lantern,as shown in the transverse section, Fig. 3, thus bracing the upperportion of the lantern, and

preventing any twisting action upon the hinge In testimony whereof Ihave signed my name to this specification in the presence of twosubscribing witnesses.
